Yes 'Dartskipper' they were Deltic powered.
As you may know the Napier Deltic marine engine had a bumpy beginning in the RN. A simple explanation - for a very complex issue - coolant entering cylinders when shut down for any length of time.
By the time the Norwegian 'Nasty' class entered the scene (1960's), the issue had largely been identified and remedied, with the 20 or so vessels of the USN serving with some distinction I believe in Vietnam??
